Issue AH00124: Request exceeded the limit of 10 internal redirects.....

[LionKing]

Server operating system version

Linux Ubunto 22.04

Plesk version and microupdate number

Plesk Obsidian Web Host Edition Version 18.0.57 Update #5

I'm seeing this error in our main company website is crashing I'm not sure what is causing it...

AH00124: Request exceeded the limit of 10 internal redirects due to probable configuration error. Use 'LimitInternalRecursion' to increase the limit if necessary. Use 'LogLevel debug' to get a backtrace.

I've changed the log level to "All" in PHP settings. But so far it doesn't reveal any clues to me.

Any ideas?

Thanks in advance.
Kind regards

The preferred URL in Hosting Settings or the SSL settings do not match the configuration of the website. Example: As the "preferred URL" you have defined the "www." spelling, but in your Wordpress you have defined the domain without "www".

We always use the non www versions on our servers because there is no need to use "www".
Someone thought it was cool with "www" when the internet was built but totally unnecessary from practical use.

So how can we remove/fix this issue @Peter Debik ?
Kind regards

Have you considered looking into your configuration and - for example - setting the preferred URL in "Hosting Settings" to "none"? Did you actually have a different setting there? Did you check your SSL settings - for example the permanent SSL redirect and the SSL settings in your website to match?

Hi
I have tested your suggestion but it does not make a difference when you set it to "none". The error message still shows up.

I did a search for this issue again and found this Plesk KB article which actually refers to the .htaccess file:
Website fails to load due to internal redirects: 500 Internal Server Error - Support Cases from Plesk Knowledge Base

However the suggestion:
# BEGIN WordPress RewriteEngine On RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}] RewriteBase / RewriteRule ^index.php$ - [L] RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule . /index.php [L]
refers to single/standalone version of WordPress. Not the WordPress Multisite version (Which we use in our company), .htacess file so I do not know what would look like.

Did you also check your SSL/non-SSL setting? Are web server and Wordpress in sync for that?

In "Hosting" settings?

Not only in Hosting settings. You need to define this in Hosting Settings, but you also must make sure that the website uses the same setting. It's the same principle as for www/non-www URLs. You either use https or http, but not a mixture of both.

When we set this up (installed WordPress multisite etc.) we already this did this. We never use "www" version as it is obsolete. So the webserver and our installation is a 100% match.

Check again. There must be a loop somewhere.

I think "internal redirects" issues are more likely the result of some conflicting or bad .htaccess configurations/settings. These links might be useful:

Thank you, I will definitely check that.
